how to unblock a 2 ft wide culvert pipe?

[Neddy flanders]

so concrete pipes 2ft diameter and over 30m in length have a blockage somewhere in the middle. probably logs, grass debris etc.

drain rods useless, tried steel poles etc, but to no avail.

any tricks anyone??

Do you have a 2” water pump and lay flat hose? I've regularly unblocked culverts by water jetting back up the pipe. I have a firemans nozzle on the end of the layflat.

Small child on a length of rope .

On a much smaller scale (4 " pipe ) baler twine pulled through with a T shirt tied on to it and then backwards and forwards works well. Rope and a ton bag maybe?

Scaffolding poles and mechanical assistance? (Pushed up with a bale spike)

I've seen an anvil dragged through on the end of a chain, worked very well, put a rope through first, then drag chain with rope and attach anvil to end of chain

Put an oxygen bottle base first in the pipe. Put on PPE. Use an axe to knock the tap off.


Don't do this.

If you cannot get anything past it then push draining rods from either end to work out where the blockage is then fire up the digger.
This is assuming it is not under a shed.

Dynamite ?

Good going drain jetter, if it doesn't clear it, it will get through to the other end then wire rope or chain and do as above

I could actually see that working

thought about this, but struggling to get string/rope through as cant get rods all the way through. may tie a tennis or pingpong ball on end and try floating it down

Years ago the tractorman at a nearby farm had a very long "draining wire" . It was 2 lengths of fence wire twisted together into a spiral, and a handle formed by making 2 90 degree bends near the end. He liked it as you could wind it up through a blockage and it would go up a stone drain which a rod wouldn't. If all else fails would it be worth making one?

Our drainage board use an old tyre just smaller than the pipe and pull it through. Obviously you need to get a rope through first. Slurry tanker full of water may help.

Our drainage board pull a 40 gallon drum though on a length of chain.

If you can get at it a slurry tanker full of water

Don't laugh, but I have heard tipping a packet of biological washing powder down the up stream end will sometimes get things moving.

How big a pack? Tonne bag?

Can you send a camera down and see what you are dealing with?
